No, because there needs to be a third angle.
No, because there needs to be a third angle.
Yes, because it would be a right triangle.
Yes, because it would be a right triangle.
No, because a triangle must have an obtuse angle.
No, because a triangle must have an obtuse angle.
Yes, because 90 + 90 = 180.
Yes, because 90 plus 90 equals 180 .
No, because there needs to be a third angle.

To find angle b, we need to use the property that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles.
Given that angle b is an exterior angle, and the other two angles in the triangle are not specified, we cannot determine the exact measure of angle b. Therefore, we cannot provide a specific answer from the given options.
What is the sum of the measures of the interior angles at vertex I and vertex J ?
